CS35L01/03
26 DS909F1
Note:
18. “Idle Current Draw vs. VBATT - HD Mode” capacitor values refer to C
FILT
when configured as the
“CS35L01/03’s Minimized Optional Output Filter”, shown in Figure 5 on page 17. When VBATT is
below “VBATT Limit for HD/FHD Mode” (VB
LIM
), operation is restricted to SD Mode.
